Unilateral Lung Over-crowding In the course of Exercising in a Individual Which has a Single Lung Problematic vein Stenosis.
The aim of the current study is to identify distinct cytokine profiles in relation to self-perceived cognitive trajectories. In our study cohort (n = 128), early-stage breast cancer patients were categorized into no impairment reported, acute, delayed, persistent and intermittent cognitive decline respectively. Pro-inflammatory cytokines were elevated compared to baseline; with TNF-α implicated in the acute cognitive trajectory while IL-6 and IL-8 were involved in the persistent cognitive trajectory. Our findings help to further our understanding of cytokine profiles implicated in cancer-related cognitive impairment (CRCI) and support the use of cytokine levels as biomarkers of cognitive decline over time. BACKGROUND Insomnia and depression are highly prevalent perinatal complications. Ruminating on stress is etiologically implicated in both disorders, and ruminating while trying to fall asleep has been linked to insomnia and depression during pregnancy. Incompatible with rumination is everyday mindfulness, i.e., living with intentional and nonjudgmental awareness of internal and external experiences in the present moment. Responding to stress mindfully may protect against stress-related perinatal complications such as insomnia and depression. The present study described the association between everyday mindfulness and nocturnal rumination, and examined whether these trait characteristics were independently related to perinatal insomnia and depression. METHODS Cross-sectional and secondary analysis of existing data from 65 pregnant women recruited from a multisite hospital in Metro Detroit, MI, USA. Subjects completed online surveys including the Insomnia Severity Index, Edinburgh Postnatal Depression Scale, Presleep Arousal Scale, and the revised Cognitive and Affective Mindfulness Scale. RESULTS Over half (53.8%) of women screened positive for clinical insomnia and 12.3% screened positive for major depression. Women high in mindfulness, relative to those low in mindfulness, reported less nocturnal rumination (Cohen's d=1.16), insomnia symptoms (Cohen's d=1.24), and depressive symptoms (Cohen's d=1.35). Multivariate linear regression revealed that both mindfulness (β=-.24, p=.03) and rumination (β=.38, p less then .01) were independently associated with insomnia. Similarly, a multivariate model showed that mindfulness (β=-.41, p less then .001) and rumination (β=.35, p less then .01) were independently associated with depression. CONCLUSIONS Ruminating in bed at night is strongly associated with insomnia and depression during pregnancy, whereas mindfulness may potentially protect against these stress-related perinatal complications. OBJECTIVE The present study investigated the relationship between difficulty initiating sleep and depressed mood and whether it is mediated by repetitive negative thinking. A moderating role of perfectionism was also examined. METHODS We surveyed 393 adolescents aged 14 to 20 years (M = 17.32, SD = 1.90) via an online questionnaire that assessed difficulty initiating sleep, repetitive negative thinking, perfectionism, and depressed mood. RESULTS Results indicated that repetitive negative thinking fully mediated the relationship between difficulty initiating sleep and depressed mood. In addition, this relationship was moderated by perfectionism, specifically, the relationship between repetitive negative thinking and depressed mood was stronger among more perfectionistic adolescents. CONCLUSIONS These findings highlight that repetitive negative thinking is significantly associated with both difficulty initiating sleep and depressed mood, supporting the conceptualization of repetitive negative thinking as a transdiagnostic process. Further, individual differences in perfectionism may amplify the relationship between repetitive negative thinking and mood. The role of repetitive negative thinking and perfectionism in explaining the link between sleep onset problems and depressed mood has important clinical implications through providing possible treatment targets. BACKGROUND Pediatric asthma remains a public health challenge with enormous impact worldwide. OBJECTIVE The aim of this study was to identify and prioritize unmet clinical needs in pediatric asthma, which could be used to guide future research and policy activities. METHODS We first identified unmet needs through an open-question survey administered to international experts in pediatric asthma who were members of the Pediatric Asthma in Real Life Think Tank. Prioritization of topics was then achieved through a second, extensive survey with global reach, of multiple stakeholders (leading experts, researchers, clinicians, patients, policy makers, and the pharmaceutical industry). Differences across responder groups were compared. RESULTS A total of 57 unmet clinical need topics identified by international experts were prioritized by 412 participants from 5 continents and 60 countries. Prevention of disease progression and prediction of future risk, including persistence into adulthood, emerged as the most urgent research questions. selleck Stratified care, based on biomarkers, clinical phenotypes, the children's age, and demographics were also highly rated. The identification of minimum diagnostic criteria in different age groups, cultural perceptions of asthma, and best treatment by age group were priorities for responders from low-middle-income countries. There was good agreement across different stakeholder groups in all domains with some notable exceptions that highlight the importance of involving the whole range of stakeholders in formulation of recommendations. CONCLUSIONS Different stakeholders agree in the majority of research and strategic (eg, prevention, personalized approach) priorities for pediatric asthma. Stakeholder diversity is crucial for highlighting divergent issues that future guidelines should consider. BACKGROUND/PURPOSE The World Health Organization has recommended commercial urine-sourced lipoarabinomannan (LAM) detection as a tool for screening HIV patients with suspected TB, but more sensitive immunodetection assays would help to identify HIV-negative TB patients. Here, we aimed to develop novel rabbit monoclonal antibodies (mAbs) against LAM for immunodetection purposes. METHODS Rabbits were immunized with cell-wall components from the Mycobacterium tuberculosis (Mtb) H37Rv strain. An immune single-chain fragment variable (scFv) phage display library was generated. The scFv mAbs to LAM were identified through ELISA screening. The light and heavy chain variable region genes from the selected clones were sequenced. Vectors containing the full-length light and heavy chains were constructed and co-expressed in 293 T cells to generate whole IgG antibodies. The performances and binding characteristics of the mAbs against purified LAM from M.tb H37Rv, multiple mycobacteria species (M.tb H37Rv, M. bovis and non-tuberculous mycobacteria (NTM) strains), and mycobacteria clinical isolates (Mtb and NTM isolates) were determined using various immunoassay methods.
